Stowaways
I found two small dogs.
I was waiting in the line at security behind a lady with two bags. She puts both bags down on the conveyor belt and opens one up to grab something. One of the dogs decided this was its cue to make itself known and popped its head out the bag. The security line was halted and she was asked to open the bags revealing not just the first dog but another one. I really have no idea what was going through her head.
